Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a rubber shoe in which hair or short fibers are implanted in the shoelace, and a method for manufacturing the same.

(Prior art) Shoes with a cover made of hair or short fibers or a densely grown sheet-like material have an elegant appearance and are classy as fur shoes, suede shoes, etc. It has a warm image and is heat-retaining and cold-proof.

However, since these shoes are mainly made of fur or fibers, there is no problem when they do not get wet with rain or water, but if they do get wet with rainwater or snowmelt water, water leakage or capillary phenomenon may cause the shoes to deteriorate. Water penetrates into it. The color change, contamination, deformation, etc. caused by the wetness impairs the appearance, and the shrinkage makes it difficult to wear and uncomfortable to wear, as well as impairing durability. Especially in winter, getting wet feet is an extremely unfavorable problem from a sanitary and health standpoint.

Therefore, a method for manufacturing footwear having a fur coat made of a sheet-like material whose surface is flocked with soft hair (patent application publication 1970-29700)
There are synthetic resin footwear made of flocked short fibers, and rubber footwear molded from a vulcanized rubber sheet with flocked flocks (Utility Model Application Publication No. 133803/1983).

The former is a method of manufacturing footwear in which a band-like piece having a bulge S on the upper edge is sewn around the lower edge of a band made of a sheet-like material with dense hair, suspended over the last of the foot, and a sole member is attached. .

In the latter case, short fibers are flocked to a synthetic resin sheet or short fibers are flocked to an unvulcanized rubber sheet, which is then vulcanized, and then a cover is made.

(Problems to be Solved by the Invention) As mentioned above, in the former case, in order to surround and sew the band-like piece having the bulge on the upper edge to the lower edge of the densely covered hair, a specially-shaped band-like piece or the like is used. It required a lot of work such as sewing and was expensive.

In addition, water and melted snow permeate through the threads and holes created by sewing due to capillary action, making it difficult to wear and uncomfortable to wear, as well as reducing durability. there were. Especially during the winter season, this was an extremely serious problem in terms of hygiene and health. In addition, fur shoes and shoes made mainly of fibers were contaminated and deformed due to shrinkage of the covering, which impaired their appearance and made them difficult to wear. Therefore, it was impossible to wash the contamination that had soaked into the cover due to shrinkage and deformation.

In addition, in the latter case, the hair cover before molding is made of synthetic resin 1c (fluffed) or is vulcanized after being flocked to a rubber sheet, so it is flexible or elastic. Therefore, since it is difficult to mold and hang the molds by hand, these require expensive machinery and highly skilled techniques, and are expensive due to poor efficiency.

Furthermore, the adhesive on the bottom cannot be guaranteed to be perfect because it is so-called post-installation, and the appearance may be damaged due to peeling or adhesive protrusion.

Due to the various extremely difficult problems described above, this type of rubber shoe has never been available on the market despite a strong demand.

(Elaborate Means for Solving the Problems) The present invention relates to flocked rubber shoes that solve the above-mentioned drawbacks and how to deploy the shoes. That is, adhesive is applied to the insole and the buried sole, these are pasted and placed on the bottom of the shoe mold, and other parts other than the part that is bonded to the sole etc. are coated with adhesive. The jacket is made of unvulcanized rubber and is made of flocked hair.
These flocked rubber shoes are characterized by being hung and attached to the inner sole, then attached to the outer sole, and then vulcanized by a conventional method.

In addition, in order to solve the above-mentioned drawbacks, there is a process of applying adhesive to the insole and the buried sole, then pasting them and placing them on the bottom of the shoe mold, and an unvulcanized rubber sheet. , a step of applying an adhesive to other parts of the head cover other than the adhesive part with the bottom part, and then flocking thereto, and a step of cutting the head cover,
A method for manufacturing rubber shoes with flocked hair, which comprises the steps of placing a jacket over a mold, suspending it, and attaching it to an inner sole, and then attaching an outer sole, and vulcanizing by a conventional method. It is.

In addition, in the above, the term "fleece-flocked to other parts with adhesive except for the adhesive allowance to the bottom" means that the fuzz is flocked uniformly over the entire other part, or partially, i.e., with a pattern or This includes cases where hair is implanted in fashionable designs.

(Function) The flocked rubber shoes of the present invention have perfect adhesion between the laces and the outer sole, and there is no sewing at all, so there is no risk of water leakage even if they get wet. It is completely waterproof. In addition, since it is flocked, there is almost no direct contact with the rubber even when it comes in contact with snow, so it has cold protection and heat retention.

In addition, regarding a method for manufacturing rubber shoes with flocked hair, which is another invention, by not flocking the hair in the adhesive part of the shoe cover and the outsole, and by molding the shoe in the state of unvulcanized rubber, the shoe cover and the outer sole are bonded. The adhesion is perfect, and the forming of the jacket, hanging, etc. can be done manually as before, making it easy. Therefore, the finished appearance is also beautiful.

(Example) An example of the present invention will be described with reference to the drawings. 1 to 6 show a first embodiment.

First, as shown in FIG. 3, an adhesive is applied to the unvulcanized rubber sheet 11C% on the outer sole except for the adhesive portion 11, which is the adhesive portion to the outer sole, and then Vc1 is applied. At the same time, for convenience when cutting, hair is also planted at the place where the blade comes into contact as a cutting mark 22. In the above-mentioned case, the hair may be transplanted partially, ie, in a pattern or a fashionable design.

A screen is used to apply the adhesive. (Not shown.

) Attach the required hair-planting cover and cut-out sheets at the cutting marks to the screen.

Note that this cutout is slightly larger than the actual cover. This screen is applied to the unvulcanized rubber sheet 1, and an adhesive is applied to the cut-out portion of the paddy. Rubber glue is used as the adhesive, and it has also been treated for flocking. Note that the adhesive varies depending on the hair and short fibers to be transplanted. As usual, hair and short fibers are treated as hair transplanters.

The flocking is carried out using an electric flocking device (not shown) and a method conventionally used for rubber. This includes a method in which flocking is carried out by continuously applying adhesive ft, and a method in which flocking is carried out separately by unvulcanized rubber sheet 1 one by one.

The 'S's of the hair and short fibers to be transplanted may be natural, chemical or synthetic and are not particularly limited. The size of the hair is also not particularly limited. The amount of electricity used by an electric hair transplantation device increases depending on the size of the hair. In addition, the thickness of polyamide fiber is 1.
If the hair is 5 denier and 0.6 length long, it will have a suede look.

Next, as shown in FIG. 4, it is cut into flocked hair 2. Cutting is generally done using a blade type. Flocked unvulcanized rubber sheet) Step 11: Can also be cut by stacking two or more sheets. Note that the cutting mark 22 is also convenient when cutting by a method other than using a blade.

Next, as shown in FIG. 5, the shoe metal fi7 is inverted, covered with the lining cloth 3, and rubber paste is applied as an adhesive to the surface.

After leaving it to dry, apply rubber glue on both sides of the buried bottom 5 and the middle bottom 40. It is applied and adhered to the lining fabric 3 on the bottom surface of the shoe shoe 7.

It should be noted that reinforcement of the cover is not necessarily required, but in general, unvulcanized rubber is then pasted on the front side 8 and the rear side 9fjr. Also, attach shoe tape io't' to the shoe opening.

next! @ As shown in Figures 1 and 2, a mantle 2 with flocked unvulcanized rubber is placed over the mantle, butted on the back, and suspended at the bottom to form the inner sole 4 or the inner sole 4 and the buried sole 5. and paste it. At the time of this hanging process, the adhesive margin 11 of the flocked haircoat to the bottom is placed at the bottom part.

As a method for this hanging process, since the position of the midsole 4 at the bottom part of the shoe mold 7 is constant, the border of the flocked part of the shoe cover is pasted and molded using this as a mark.

This makes it possible to prevent the flocked portion from overlapping the outer sole 6. In addition, due to the design, there is a certain distance t from the outer sole 6.
It can also be pasted.

Next, the outer sole 6 is attached. At this time, since the adhesive is attached to the adhesive area 11 between the cover and the bottom, the adhesive is perfect. Thereafter, the flocked rubber shoes of the present invention are completed by vulcanization by a conventional method, and the manufacturing method thereof is completed. If necessary, a rubber paint may be applied and vulcanized after the outer sole 6 is attached. Since the scrap rubber produced during the cutting process, the wrapping process, the hanging process, etc. is unvulcanized, it can be re-rolled and used as other parts.

Next, a second embodiment of the present invention shown in FIGS. 6 to 13 will be described. FIG. 6 is a perspective view of the 8g2 embodiment, and FIG. 7 is a partially enlarged end view taken along line Q-Q' in FIG. 6 1c.

As shown in FIGS. 8A and 8H, the left and right sides of the cover are separated, and the adhesive is applied as in the first embodiment.
T! 1. Hair transplanted as in Example 1, hair transplanted t hair 2a, 2b
get. The shape of the application of the adhesive and the flocking are developed to match the three-dimensional shape of the shoe mold 7. This is to facilitate the forming of the hair-flocked hair coat 2 into a mantle and hanging it, and to eliminate heat-free work such as hair-flocking. In addition, the hair transplanted hair on the left side 2
a, the right side cover 2b is approximately symmetrical.

At the time of the above-mentioned hair transplantation, the left side hairpiece 2a and the right side hairpiece # As a cutting mark, the part S'1gI where no hair is implanted is placed about 5 points from the front at the upper end of the hair transplanted hairpiece 2:, the hairless hairpiece on both sides of the hairpiece. 2
It is not necessary to attach it to a and 2b. This is used when cutting and gluing the pieces 2a and 2b on both the left and right sides of the cut root overlapping each other.

Next, as shown in FIGS. 9A and 9B, the left and right hairs 2a and 2b, which have been flocked with hair, are cut using a cutting blade.

After that, as shown in FIGS. 10 and 11, the left and right side covers 2a and 2bY are overlapped. At this time, overlap them so that the inner sides that are not grafted are in contact with each other. Of course, two or more sets may be stacked at the same time. The cutting blade shapes are aligned and cut from the upper end cutting mark S to the lower end cutting mark T of these uppermost rows.

As a result, the structure shown in FIG. 12 is obtained, and the left side hairpiece 2a and the right side hairpiece 2b with flocked hair are adhered to each other at the front end W.

If both sides are butted together with the front end W being glued as the center, the entire surface will be glued, but rolling it will make it more perfect, and the integral flocked hair cover 2 will become three-dimensional. This is because the left and right side covers 2a and 2b are made of unvulcanized rubber, so they easily come into contact with each other.

Therefore, it is effective to overlap and cut these pieces 2a and 2b in a soft state.

Next, as shown in FIGS. 7 and 13, as in the first embodiment, the inner sole 5 and the front side 8. Attach the rear sword 9 and the cuff tape 10. Furthermore, back tape 12 and hem tape 13 are pasted.

On top of these, the flocked nine-piece jacket 2Y obtained as described above is applied, and is attached to the inner sole 4 and the buried sole 5, and suspended. In this case, since the flocked hair cover 2 is three-dimensional so as to fit with the shoe mold 7, the above-mentioned operation can be easily carried out without having to pull strongly in parts as in the first embodiment.

Next, the outer sole is 6y! - By pasting and then vulcanizing in a conventional manner, the flocked rubber shoes of the present invention are completed and the manufacturing method thereof is also completed.

In the above embodiments, rubber shoes with summer cloth are described, but shoes without lining can also be manufactured. In this case, as with conventional rubber shoes of this type, the back of the unvulcanized rubber cover is pasted to form a so-called cylinder, and then the shoe mold is covered with the inner sole and suspended. The rubber shoes are then flocked by molding and vulcanization in the same manner as described above.

Furthermore, although each of the above-mentioned embodiments relates to rubber shoes with flocked hair on the front side of the shoe cover, rubber shoes with flocked hair on the back side can also be manufactured.

In this case, turn the hair-planted nine-piece cover inside out, stick the required part of the cover with the flocked part on the inside, make it into a so-called cylindrical shape, and place the cover directly on the shoe mold.1. After that, the outer sole etc. are attached in the same manner as described above, and vulcanization is performed by a conventional method.

(Effects of the Invention) As mentioned above, one of the features of the present invention is to attach a patch made of unvulcanized rubber to a shoe mold with hairs implanted in other parts than the adhesive part with the outer sole using an N agent. These flocked rubber shoes are manufactured by covering the shoe, hanging it up, and attaching it to the inner sole, and then vulcanizing the outer sole by a conventional method after fixing.

Therefore, these rubber shoes have the properties of rubber shoes, and because they are flocked, they have an elegant appearance and are tasteful, and have a high-class image as fur shoes or suede shoes.

Since the cover is made of unvulcanized rubber and the bottom is glued to the area without flocking, the adhesion is perfect and there is no risk of it peeling off, making it completely waterproof.

Therefore, there is no need to surround and sew a band-like piece having a bulge on the upper edge to the lower edge of the sleeve as in the conventional case.

Therefore, even if it comes into contact with rainwater or snowmelt water, there will be no water leakage or penetration, so there will be no deterioration in appearance or discomfort, and the durability is good. Incidentally, the flocked rubber shoes of the present invention have the characteristic that dirt can be restored cleanly by washing with water.

However, since there are hairs and short fibers on the surface, snow and cold air rarely come into direct contact with the rubber iC, so it has heat retention and cold protection.

In particular, in the past, heat insulating materials, cold protection materials, etc. were made thicker in multiple layers in order to provide heat retention and cold protection. However, the rubber shoes with flocked hair according to the present invention simply have hair flocked on the rubber. In addition to having heat retention and cold protection, the structure and manufacture are extremely simple, and it is light and fits well on the feet, making it comfortable to wear. Therefore, although they have the same appearance as fur shoes or suede shoes, they have excellent durability and are economical because they can be manufactured at a relatively low cost.

Still another invention is a method for manufacturing flocked rubber shoes.

That is, excluding the process of applying adhesive to the insole and the buried sole, pasting these, and placing them on the bottom of the shoe mold, and the adhesive part of the sole of the unvulcanized rubber sheet and the cover. The method includes the following steps: a step of flocking the hair to other parts, a step of cutting the head cover, a step of hanging the head cover and forming the outer sole, and a step of vulcanizing by a conventional method. That is.

Therefore, the part of the shoe cover that is attached to the sole is not flocked with hair, and since the hair is flocked and the shoe mold is covered with unvulcanized rubber, and the shoe mold is suspended, the shoe cover is flexible. It is easy to work with, and the bottom is completely bonded, and there is no adhesive protrusion or poor hanging, so the appearance is not damaged. or,
Since there is no need to puff the cover and apply adhesive, it is efficient and can be produced at low cost.

In addition, as in the second embodiment, the hair was divided into two parts on the left and right and the hair was implanted.
After that, in the process of gluing these pieces together and putting them on the L1 shoe mold as a single piece, and suspending the molding, it is possible to fit the shoe mold perfectly with almost no stretching. Therefore, these operations are easy and rubber shoes of uniform thickness can be efficiently manufactured.

Furthermore, it goes without saying that the present invention can be applied to all types of shoes, including short shoes, single-piece boots, and any type of rubber shoes, regardless of the presence or absence of lining fabric, or whether or not the front needles of the laces are implanted. Furthermore, in the step of flocking, rubber shoes can be made with a reasonable design by forming a pattern by changing the hair color, length, presence or absence of hair, etc.

In addition, in the invention related to the manufacturing method, since the burlap is cut at the stage of unvulcanized rubber, cutting scraps are produced, but even if there is some flocking, the unvulcanized rubber can be kneaded with rolls as before, and other It can be used again.

Therefore, unlike conventional vulcanized rubber scraps, it saves resources and is therefore less expensive.
